EXCELSIOR-MACHINE.

SPECIFICATION forming part of Letters Patent No. 499,168, dated June 6,1,893.

Application tiled July 5| 1892. Serial No. 438,854. (No model.)

To all whomit may concern:

Be it known that l, BART KANE, a citizen of the United States, and aresident of Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Machines for MakingExcelsior, of which the following is a specification.

My invention 'relates to improvements in machines for making excelsior.are to provide a machine which may be kept continually in operation at ahigh speed, produce the least possiblewaste of material, have few partsto get out of order or require attention, does not require skilled laborto operate, and is not dangerous to the attendant.

The invention will be lirst fully described in connection with theaccompanying drawings, in which like parts are indicated by similarreference letters wherever they `occur throughout vthe variousviews,land afterward. its novel features will be particularly referredto andpointed outin the claims. l

Figure l is a side elevation of myimproved machine with one of the feedchutes removed to expose the parts back of it. Fig. 2 is a transversesectional View of the same taken through line w. of Figfl. Fig. 3 is asimilar section through line y. y. showing an inverted plan view of thecutter Wheel and its Fig. 4 is a detail View upon an enlarged scalepartly in side elevation and partly in central longitudinal section ofthe attachments for scoring the face of the block in advance of thecutting blades, the frame holding the scoring blades being in itscentral position. Fig. 5 is acentral transverse sectional view of thedevice shown in Fig. 4 upon the same scale.

The frame of the machine within and upon which the operative parts aremounted is preferably formed of the upper and lower cross framed piecesA... A. braced firmly by the uprights A2 and a similar cross frame A3the ends of which are tenoned to enter vertical grooves in the innersides of the uprights A2 to which it is secured in its lower position bybolts a. The shaft B which carries the cutter wheel C, has its lowerbearing in a step b centrally secured upon the frame A. It

. passes through the frame A.3 and has its up- Its objects per bearingon the frame A. Upon the uptheir edges may be projected above thecutterA Wheel to takethe requisite bite on the blocks l fed down uponthem through the chutes E ofwhich there are four. VThese chutes aresecured in a vertical position between the arms of the cross-frames,AYAS, and extend as shown to the top of the frame, but it is theintention to carry them up to the door or room above that in which'themachine is operated 'in which the blocks are prepared and fed into thechutes. The chutes thus being always kept full of the blocks the lowerones will beheld against the action of the cutters by the weight ofthose above them, and the necessity.

of weights, springs, or other inconvenient contrivanc'es, to hold theblock While acted upon is dispensed with.

The scoring blades f are clamped in a rectangular open box or frame F,,between Hat steel bars f which space the scoring blades the properdistance apart to make strands of the required size, by a set screw(shown in dotted line)` which is tapped through the end of the frame.

per extended end of the` shaft is secureda I The frame F, is heldbetween the forked ends of a pivot pin F which pin is pivoted in ahanger G, depending from an open box or frame H. The ends of the frameF, areoverlapped by plates h secured across the ends of the frame H.These plates steady the frame F, as it vibratesupon its pivot in eitherdirection Within the frame H. The sides ofthe frame H are beveled to fitwithin a radial slot in the edgeof the cutter wheel. The walls of theslot A are inclined counter to the edges of the box kH, which is adaptedto slide within the slot in the cutter wheel and is confined in place byplates h',

IOO

secured to the under side of the wheel to overlap the edges of thesliding boX; The box is held within the slot by clips h2 which aresecured in the edge of the cutter wheel and overlap the edges of theradial slot. The box H is normally held against these clips andin itsouter position by coiled springs h3, which are seated in holes in theinner Wall of the slot, and press against the inner end of the box H.

The frame F, is normally held at an angle to the radii of the cutter by'coiled pulling springs f2, which are connected to its opposite ends andto studs secured in the under face of the wheel C, for the purpose ofpresenting the scoring knives in the proper po sition to the end of theblock, and gradually i introducing the guide pinsf, which depend" fromeach end of the frame F, between the guide plates I, which compel theframe F, to travel parallel to the sides of the feed boxes while actingupon the blocks fed to the cutters. shaped angle bars set upon angl-efeet i', which are secured upon the crossframe A. The horizontal Webs ofthe guides I are slotted to passthe Shanks of bolts fi', which aretapped into thefeet. By this means the guide plates are made adjustabletoa compensate for Wear,and for convenience in` properly adjusting partswhen the machine is set up. There are of course guides opposite: thedischargeof each chute but only one set' is shown.

To the underside ofthe cross arms of'frame A3, are secured ribs a whichproject down below?` the lower edge of the feed chute, and are arrangedat'` a tangent to theV path of travel` of the knives c, for the purposeof discharging the slabs or slizvers left from the top of theblocksabove the wheel. So soon asa block is so nearly used up that itstop comes below the edge of the feedfchute,.one of the cutting knivesstriking itwill drive it from under the chute and the rib will guide itscourse to the outside of the machine.

The machine when set up for use is` mounted upon standards or anv openframe Work some distance above the ioor and the bottom part The guides Iare preferably madey of L` from near the upper face of the cutter wheelto base incased bya sheet metal coverso that the excelsior is dischargedbelow in a convenient position to be removed while the slabs or sliversare discharged by centrifugal force at t some distance fromthe finishedstock.

It will be obvious to those skilled in the art after an examination ofmy improved machine that many mechanical changes and sub- 1 stitutionsmay be made in some of the parts without varying theprinciple or mode ofoperation of the machine and I would hence y have it understood that Ishould consider such mere mechanical deviations as within the spirit andscope of my invention.

1. The combination substantially as speci fied in an excelsior machineof the cutter wheel C, radially slotted to receive the frame carryin gthe scoring blad-es, and the cutting knives 10, secured in said Wheel,the vertically arranged feed boxes, the radially sliding frame H,carrying the frame holding the scoring blades, the hanger G, dependingfrom the `frame H,theframe F, pi-votcd in said hanger, the scoringblades carried in frame: 1F, the springs to hold. the scoring bladesnormally at right angle ,to the ends of the feed boxes, and the guides Ito carry the scorer parallel to the sides ofthe feed boxes fol-'thepurpose vset forth.

2. The combination of the frametl1evertilcal` shaft and cutter wheelmounted to revolve therein, the cutting knives secured insaid wheel, thefeed boxes to feed the. blocks to the cutters, the frame H, fitted toslide radil ally in the cutterWheel-,th'c frame F carrying the scoringblades pivoted to vibratev Within `the frame l-l, the guides to carrythe scoring devices parallel with the' sides ofA the feed boxes, and theribs ai', arranged above the cutters` to discharge the slivers outsideof the frame and away from the finished stock substantially as shownandV described.
